Typhimurium對這些消毒劑之耐受性。在另一方面經過冷震處理後之V. parahaemolyticus、Sal. Typhimurium及L. monocytogenes菌體暴露於Clidox-S®及Quatricide®之耐受性亦顯著提高 (p < 0.05)，而在40oC下，Clidox-S® 及Quatricide® 對所試病原菌呈現之抗菌效果均比在25oC下強。This study was conducted to investigate the effct of heat shock and cold shock on the susceptibility of various food-borne pathogens such as Vibrio parahaemolyticus, Salmonella Typhimurium and Listera monocytogenes to sanitizers including Clidox-S® and Quatricide®. It was found that heat shock treatment significantly (p < 0.05) increased the tolerance of V. parahaemolyticus and L. monocytogenes to Clidox-S® and Quatricide®, while reduced the tolerance of Sal. Typhimurium to these sanitizers. On the other hand, a significantly (p < 0.05) increased tolerance to Clidox-S® and Quatricide® was noted with cells of V. parahaemolyticus, Sal. Typhimurium and L. monocytogenes after exposure to cold shock treatment. Additionally, Clidox-S® and Quatricide® exhibited a higher antibacterial activity against the pathogens examined at 40oC that at 25oC.2858504 bytesapplication/pdfen-USVibrio parahaemolyticusSalmonella TyphimuriumListeria monocytogenes熱震冷震消毒劑Heat shockCold shockSanitizers熱震與冷震影響一些食源性病原菌對消毒劑之敏感性Heat and Cold shock Affect the Susceptibility of Various Food-borne Pathogens to Sanitizersthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/248311/1/ntu-99-R97641005-1.pdf
